WSDL soap:header with java

hi everyone:

I am encountering a problem when generating java stub from a wsdl using java.

Basically,

I have a binding in WSDL like this:

  <binding name="Connection_Operations" type="tns:Connection_Operations">

    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

    <operation name="Logout">

      <soap:operation soapAction="function=Logout"/>

      <input>

        <soap:body use="literal"/>

        <soap:header message="tns:SecureConnection" part="session" use="literal">

        </soap:header>

      </input>

      <output>

        <soap:body use="literal"/>

      </output>

    </operation>

</binding>

And the operation is deinfed as this:

    <operation name="Logout">

      <input message="tns:Logout_Input"/>

      <output message="tns:Logout_Output"/>

    </operation>

The input message is deinfed as:

  <message name="Logout_Input">

  </message>

When I generated the java soap stub for the logout, "session" has no input parameter, so I have no way to set the soapHeader information.

how I can add this variable to the header?
